Daru (Data Analysis in RUby) is a library for analysis, manipulation and visualization
of data. Daru works seamlessly accross interpreters and leverages interpreter-specific
optimizations whenever they are available.
It is the default data storage gem for all the statsample gems (glm, timeseries, etc.)
and can be used with many others like mixed_models, gnuplotrb, nyaplot and iruby.
